{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"A choropleth map displays countries colored by economy group, with an interactive color legend that filters the map by hover or click. Clicking a legend item highlights matching countries and dims the rest, while clicking again clears the filter. The visualization uses d3.geoPath with a geoNaturalEarth1 projection for country shapes, d3.scaleOrdinal with a schemeSpectral range for coloring, and loads world data from the world-atlas package. A d3.zoom interaction supports panning and zooming the map.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e39e0599734d4816b115fc014aee63a2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
